How is Flux Calibration Done at Radio Wavelengths?

-- | October 16, 2016

Question: I want to know strategy for flux calibrator please help me how to do it if I have a given DATA. — Jagriti

Answer: Flux calibration for radio astronomical measurements is normally done by observing an astronomical source of known or predictable flux along with the measurements of the target source of interest. The flux calibrator chosen depends upon what frequency you are observing at, and can include quasars, planets, or asteroids.

The National Radio Astronomy Observatory is a facility of the U.S. National Science Foundation operated under cooperative agreement by Associated Universities, Inc.
	Founded in 1956, the NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.
	The U.S. National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 "to promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense..."
	AUI collaborates with the scientific community and research sponsors to plan, build, and operate cutting-edge facilities. We cultivate excellence, deliver value, enhance education, and engage the public.
